Re: EventListener and PropertySelection (Solution)
I just run into the same exact thing, using Tap 4.1.5, dojo that comes with
it, propertyselection and an eventlistener as well as prototype. Anybody
know if this is fixed in a newer snapshot, if there is a bug open on this or
any (better) workaround?

Re: EventListener and PropertySelection (Solution)
Posted by Kalle Korhonen <ka...@gmail.com>.
Here's a solution that's still a bit ugly but at least a little less drastic
than commenting out parts of Dojo... Override dojo.dom.isNode in your code
as follows:
dojo.dom.isNode=function(wh){
if(typeof Element=="function"){
try{
//return wh instanceof Element;
return Object.isElement(wh);
}
catch(e){}
}else return wh&&!isNaN(wh.nodeType);
};
Obviously, you could move this to core Tapestry and check for existence of
isElement() first to make it work whether or not prototype exists. Not sure
though this is probably worth solving - don't know if there are that many
users out there using T4, dojo and prototype.
